GAS CONNECTION PIPE

The gas must be connected using steel or copper pipes, or with flexible steel pipes, in accordance with the laws of the country
where the appliance is installed.
Each appliance must be furnished with an easy-closure cutoff cock for the gas.
After installation, a check must be made for possible gas leaks from the fittings; do not use a flame for this purpose, but non-
corrosive substances, for example a solution of soapy water or a spray which makes any leaks evident.
All of our appliances undergo rigorous controls: the type of gas, the functioning pressure and the category to which it belongs
are indicated on the data plate.
CHECKING THE THERMAL POWER
Check if the thermal power is correct:
• The thermal power is indicated on the data plate of the appliance;
• First check whether the appliance is set up for the type of gas supplied, then ensure that the information on the data
plate corresponds to the gas to be used. When adapting to another type of gas, check that the characteristics of that
gas conform to the specifications given in this instruction manual.
The pressure is measured using a pressure gauge (smallest unit of measure 0.1 mbar) which is inserted in the appropriate
outlet (see figure A, pos. 10). Remove the sealing screw and insert the tube of the pressure gauge. After measurement, replace
the screw, tighten it and check if it is watertight.
Connection for liquid gas G30/G31
The connection pressure for liquid gas is 28 mbar for butane, 37 mbar for propane.
Check the data plate, measure the pressure and see whether the description of the nozzle installed corresponds with the one
given by the manufacturer.

Connection with natural gas (methane) H G20

The connection pressure of natural gas is 20 mbar.
Check the data plate, measure the pressure and see whether the description of the nozzle installed corresponds with the one
supplied by the manufacturer.
CHECKING THE PRIMARY AIR OF THE MAIN BURNERS
All burners are equipped with special injectors which do not require the adjustment of the primary air.
